Description:
With keyring_file.dll enabled in my.ini version 8.0.41 throws an exception at startup:

Most likely, you have hit a bug, but this error can also be caused by malfunctioning hardware.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

I also tested this on 8.0.21 and 8.0.36 with the same exception. Checking our release history this previously worked in 5.7.x and POSSIBLY 8.0.15 but I do not have a test case for 8.0.15 at this time.
How to repeat:
Add the following to configuration:
[mysqld]
early-plugin-load=keyring_file.dll
component_keyring_file_data ="C:/test/keyring"
Then start mysqld to observe the exception. I ran manually with --console --standalone in my description above.
It seems to be the early-plugin-load directive. component_keyring_file_data can be removed and the results are the same.
